Solution Overview

Problem

Existing screens with motorized rails for window coverings are difficult for users to install, requiring complex assembly and potential misalignment of components.

Innovation Solution

Incorporating an installation mechanism with movable suspension means and operating means at the outer ends of the motorized rail, allowing users to easily mount and lock the rail into position, ensuring accurate engagement with the guide means.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the motorized rail is designed with fixed engaging means, then the engagement with guide means is secure, but the installation complexity increases and requires precise alignment

Engineering Contradiction:
Improveengagement securityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The engaging means is designed with movable suspension means that allow dynamic adjustment during installation. The suspension means can move between a retracted position (facilitating easy installation without precise alignment) and an extended position (providing secure engagement with the guide means), thus resolving the contradiction between engagement security and installation complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The installation mechanism includes preliminary positioning features that guide the engaging means into the correct position before final engagement. The movable suspension means is pre-configured to automatically align with the guide means during installation, eliminating the need for precise manual alignment while ensuring secure engagement

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the engaging means are permanently fixed, then accidental disengagement is prevented, but installation and maintenance become difficult

Engineering Contradiction:
Improveanti-disengagementVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The suspension means is designed to be movable rather than fixed, allowing it to be easily manipulated during installation and maintenance while providing stable engagement during operation. The movable design enables users to retract the suspension means for easy removal or adjustment, yet it provides sufficient engagement force to prevent accidental disengagement during normal use

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The installation mechanism acts as an intermediary between the engaging means and the guide means. It provides a controlled interface that allows easy installation through the movable suspension means while ensuring reliable engagement, thus mediating between the conflicting requirements of ease of installation and prevention of accidental disengagement

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the screen is shipped assembled, then it is ready to use, but shipping costs and storage space increase

Engineering Contradiction:
Improveready-to-use statusVSAvoidshipping volume
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The screen is divided into separable components (frame, motorized rail, screen material) that can be shipped compactly and assembled by the end user. The modular design with standardized connection interfaces ensures that despite being shipped disassembled, the screen can be easily reassembled to a ready-to-use state, thus reducing shipping volume while maintaining ease of deployment

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The installation mechanism is designed to be user-friendly, enabling end users to easily assemble and install the screen themselves without requiring professional installation services. The movable suspension means and intuitive installation mechanism allow users to complete the assembly process independently, thus achieving ready-to-use status without the need for pre-assembly shipping

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to a screen (100), comprising a frame (3) provided with two longitudinal profiles (3A) that are to be arranged essentially in parallel, wherein guide means run in the longitudinal profiles, a retractable screen material (4) to be positioned in the frame, a motorized rail (1, 2) to which the screen material is attached and which is to be mounted movably in the longitudinal profiles, wherein in the motorized rail a drive shaft and a motor for rotating the drive shaft are accommodated, wherein engaging means are provided at both ends of the drive shaft for engaging the guide means. In both outer ends of the motorized rail an installation mechanism is accommodated, which comprises movable suspension means on which the engaging means are attached and which is provided with operating means to move and lock the suspension means into an operating position, in which the engaging means engage the guide means.
